1) The URI (e.g., https://<HOST>/mgmt/tm/sys/version) is missing in the original post. Unable to troubleshoot without the URI.
2) iControl REST was offered as "Early Access" in 11.4, hence it is not surprising to see failures in some cases. 11.5 is the GA (General Access) but it reached its End of Technical Support (see K5903: BIG-IP software support policy). My advise is to upgrade to the latest (supported) version.
